WILLIAM H. KENNEDY, OF JOPLIN, MISSOURI.

RIVETING-MACHINE fo all whom it may concern:

Be it known that I, WILLIAM I-I. KEN- NEDY, a citizen of the United States, residing at Joplin, in the county of Jasper and State reference being had therein to thel accom-v panying drawing.

My invention relates to devices for riveting, and is adapted more particularly for use in riveting girders, and other objects of large dimensions.

means for disengaging the riveting device from the article riveted; a speedy means for disengaging the operative parts; and simplicity and convenience of operation com! hined with cheapness.

To the above ends essentially my inventionl consists in the novel construction and combination of pai-ts hereinafter set forth, and

villustrated in the accompanying drawings,y

wherein,

Figure 1 is a side elevation of my novel riveting mechanism. Fig. 2, a plan of the forward portion of the same. Fig. 3, a section of the same on line w w of Fig. 2. Fig. 4, a section on line g/ y of Fig. 3, and Fig. 5, a side elevation of the same showing the parts in open position.

Like reference characters indicate like parts throughout the views.

The preferred embodiment of my inven-V tion is herein shown in conjunction with the hollow frame, 1, suspended by chain, 2, and comprising the forwardly extending horizontal upper and lower arms, 3 and 4, in vertical alinement with each other.l Fixed to the bottom of the lower arm is the cylinder, 5, which is connected with an air pump,

not shown, by pipe 6. The cylinder is pro-` vided with the usual valve, 7, for controlling the admission of air and valve lever, 8.

9 is the cylinder piston, 10 the link or connecting rod, and 11 the lower riveting die` pivoted thereto, which slides vertically in the end of the arm, 4. The heading of the rivet is done by the die, 11, whose upper endl Specification of Letters Patent.

thereof. The top of the standard is bifurcated to form vertical bearings or ears, 15,

for a pivot pin, 16. A vertically disposed opening, 17, extends through the standard, 13, arm 3, and the yoke hereinafter described, in front of the ears, 15. The opening being of less diameter near its top to form a shoulder, 18. A hand lever, 19, is pivoted forward its center upon the pin, 16, and is connected by links, 20, upon its forward end with a latch bolt, 21, slidably mounted in the opening, 17. The lower portion of the bolt is of increased diameter or lt has for its essential objects a facile thickness below its medial portion to produce a shoulder, 22. The bevel face 23 of its lower end is toward the front of the machine. The length of the bolt is such that- `lever is elevated, projects below said plane.

A compression spring, 24, surrounds a portion of the bolt, 21, with one end resting against the shoulder, 18, and the other end against the shoulder, 22, whereby the bolt is normally pressed toward its depressed or engaged position. A U shaped frame or yoke, 25, is mounted upon the standard, 13, whose arms consist of triangular plates, 26, lying in parallel planes, and whose cross portion is provided with a socket, 27, adapted to receive the shank, 28, of the anvil or die set, 29. The shank is retained in the socket frictionally or by a retaining pin or in any desired manner. The die set is provided with a cavity, 30, in its end. The plates, 26, are broad at their tops and taper downwarlflly. A hand lever, 3l, has a bifurcated or U shaped end, 32. Each leg, 32, of the bifurcated end is fixed by a screw, 33, to one of the plates, 26, at therear upper corner thereof. The forward upper corners of the plates, 26, the lever ends, 32, and the standard 13, are traversed by a pivot pin, 34, whereby, when the arm, 31, is elevated or depressed, the yoke may be swung to a horizontal o1' vertical position.

rI he operation of my mechanism is described in connection with a gir-der, 35, illustrated in Fi. 1, wherein 36 shows the rivets. The ends of the girder rest upon horses or otherwise, and the suspended frame, 1, is applied thereto. The heading die, 11, is applied to the lower or heated end of the rivet, and the die set, 29, rests upon the rivet head.

The die l1 is reciprocated from the cylinder, 5, when set in operation by the lever, 8. After the riveting operations are completed and it is necessary to disengage the frame, l, from the girder, the lever, 19, is depressed which raises the bolt, 23, into the position shown in Fig. 5, which frees the bolt from the yoke, The lever, 3l, is then elevated and the yoke brought into horizontal position as shown in the last mentioned figure.

lt will be observed that in normal or operative posit-ion the riveting or heading die and the die set are in vertical alinement with each other, and that the die set may be thrown out of alinement or elevated to any deg-ree required for the easy disengagement of any shaped piece of work.

l/Vhat l claim is,

l. 1n a portable riveting machine, the combination with a` frame comprising two lined arms, and a riveting die in one arm, ot a die-set upon the other arm and a yokesupport carrying said die-set, said yokesupport being pivotally supported from the upper arm and mounted to swing to bring the die-set into a vertical position over the riveting die or into a horizontal position beyond the end of said arm, and means engageable through the upper arm for locking the yoke in its vertical position.

2. In a riveting machine, the combination with a suspended portable frame having two fixed arms with the arms balanced, and a riveting die mounted for reciprocation in one of said arms, of a die set, a pivotal yoke support therefor mounted upon the other arm and means connected with said support 'for moving it into and out of vertical alinement with the riveting die, and means movable through the yoke and upper arm tor locking the set in vertical position.

In a riveting machine, the combination with a frame comprising` two fixed arms, of a vertical movable riveting die mounted in one arm, a standard mounted on the upper arm, a. die set, a support therefor pivotally mounted on said standard to swing into vertical alinement with the riveting die, and means fulcrumed on said standard for moving said support on its pivot to bring it into a plane above the lower edge of the arm on which it is mounted, a pivoted lever, and means carried thereby for locking said yoke in its vertical position.

4t. ln a riveting machine the combination with a frame comprising two arms, and a riveting die in one arm, of a standard upon the second arm, a yoke pivotally mounted upon the standard, a die set upon the yoke, and a` .lever fixed to the yoke.

5. ln a riveting machine the combination with a trame comprising two arms, and a riveting die in one arm, of a standard upon the second arm, a yoke comprising iat arms and a cross piece, a die set upon the cross piece, a pivot pin in the standard and upon which the voke is mounted, and a lever iXed to the tlat arms and loosely traversed by the pivot pin.

7. ln a riveting machine the combination with a Yframe comprising two arms, and a riveting die in one arm, oi a. standard upon the second arm, a yoke. pivotally mounted upon the standard and provided with an opening, a die upon the yoke, means for swinging the yoke, a belt slidably mounted in the standard regstering in the opening, a lever mounted in the standard and pivotally connected with the bolt.

S. ln a riveting machine the combination with the frame and riveting die, of a standard upon the iirame, a yoke movably mounted upon the standard provided with an opening, a die set upon the yoke, means ttor moving the yoke, a bolt slidably mounted in the standard and in the opening, spring means tor pressing the bolt into the opening, and means ulcrumed upon the standard and pivotally connected with the bolt :tor iorcing the bolt out ot the opening.

9. in a. riveting machine the combination with the trame and riveting die, ot a standard upon the trame, a yoke movably mounted upon the standard provided with an opening, a die set upon the yoke, means for moving the yoke, a belt slidably mounted in the standard, a spring in the standard engaging the bolt` a lever mounted upon the standard, and a lilik connecting the bolt and lever.

In testimony whereof I have afiixed my signature in presence of two witnesses.
